    contentformats: Change the format of gdk_content_formats_to_string()
    
    Now, we just print a whitespace-separated list of GTypes and mime types.
    
    This makes this neat for 2 things:
    
    1. Parsing it (see next commit)
    2. Using it in GtkBuilder (see commits after that)
    
    In particular, the common case of supporting a single GType (or mime
    type) looks like just printing the GType (or mime type), which in
    GtkBuilder looks like
    <property name="formats">GdkTexture</property>
